vAcUUMJs'oTTLE.

To aZZ whom it may concern:

Be it known that I, ADoLPi-I C. BECKER, a citizen of the United States, residing at Oakville, in the county of Litchfield and State of Connecticut, have invented a new and useful Improvement in Vacuum-Bottles;

and I do hereby declare the following, when.

taken in connection with the accompanying drawings and the characters of reference marked thereon, to be a full, clear, and exact description ot' the same, and which s aid drawings constitute part of this application, and represent, in-

Figure 1 a view of my improved'vacuum bottle in elevation, a portion of it being shown in vertical section, and itscase being shown in section.

Fig. 2 a broken detail sectional viewon an enlarged scale of the metal shell, showlng one of the finger-grips.

My invention relates to an improved vacuum bottle, the object being to produce the shells of such bottles with finger-grips, whereby the bottles may be more conveniently and safely handled without slipplng in the hand.

lVith these ends in view, my invention consists in a vacuum bottle having its shell provided with finger-grips, as will be hereinafter described and pointed out in the claims.

1n carrying out my invention as herein shown, the sheet-metal shell 2 of the bottle is struck up to provide it with two circumferential bands of pocket-like finger-grips, each consisting of an inwardly struck circular fiat portion 3 and an outwardly struck bead 4 surrounding the same. Since the deeper the finger-grips, the better the hold upon the bottle, the best results will be secured by striking the metal inwardly on the one hand, as much as permitted by the corrugated paper-wrapper 6 which surrounds the outer wall 7 of the bottle proper or glass container the inner wall 8 ofwhich is separated from the wall 7 thereof by a vacuum chamber 9. On the other hand, the metal of the shell 2 will be struck outwardly as much as practicable without interfering with the insertion of the bottle into the cylindrical case 10 which is furnished with a cap 11. The external diameter of the paper-wrapper 6 and the internal diameter of the case 10 constitute the predetermined limits within which the metal shell may be specification of Letters Patent.

to the shell and also assist the hand to some extent in gripping the same. The shell is also formed with a circumferential rib 13 located at its lower end and at its upper end with a corresponding rib 14, and furnished with a screw cap 15 having a rib 16 and receiving a screw cup 17, all of familiar and well known construction.

By providing the shell with two circumferentlal bands of finger-grips, my improved vacuum bottle may be handled with superior convenience and safety. 1f desired, a single band of finger-grips might be employed in place of two bands of finger-grips, or the finger-grips might be arranged in other symmetrical or non-symmetrical ways, the essential feature of my invention being the provision of the sheet-metal shell of a vacuum bottle with a plurality of pocket-like fingergrips however produced and arranged. Nor do 1 limit myself to striking the metal of the shell so as to form circular grips, as the particular form of the grips 'may be varied so long as their pocket-like character is retained.

1. The combination with a cylindrical glass vacuum-bottle, of a cylindrical sheetmetal shell therefor provided with a plurality of circumferentially arranged segregated inger-grips adapted in size to receive the tips of the i'ingers or" the user of the bottle and produced by striking the metal of the shell inwardly to form the bottoms of the grips, and outwardly to form beads around said grip-bottoms, whereby finger-grips of the maximum efficiency are secured within the limits prescribed by the glass bottle and the case into which the shell is introduced for the protection of the device as a whole.

2. The combination with a cylindrical glass vacuum-bottle, of a shock-absorbing envelop therefor, and a cylindrical sheetmetal shell having a plurality of circumferentially arranged segregated finger-grips adapted in Size to receive the tips of the lingers of the user of the bottle and produced by striking the metal of the shell inwardly to form the bottoms of the grips, and outwardlyto form beads around said gripbottoms, whereby finger-grips of the 1naXispecification in the presence of two submum ecercy 2re secueg wthn tlelmts scribing witnesses.
